Title: Chemical fluid or diffusion resistant composite tube e.g. for potable water pipe
Inventor: IMGRAM FRIEDRICH
IPC: F16L58/10
Filed: 1991-09-11
Abstract: An extruded, thermoplastic, e.g. crosslinked PE, tube (27) is conventionally heated above its crystalline m.pt. and compressed in a mould to reduce its circumference by 10-20%, and it is cooled below its m.pt..     This deformed tube (27) is inserted full length in a corrosion-resistant metal tube (26) of slightly larger bore and together heated above the crystalline m.pt., when the plastic tube (27) recovers to fit tightly in the metal tube (26), forming a composite (24). The bore of the metal tube is less than the fully-recovered (unstained) dia. of the inner tube.     Pref. metal tube (26) may be of stainless steel and have a coefft. of thermal expansion less than that of the thermoelastic polymer.     A coupling agent may be between the adjoining surfaces.     The assembled tubes (26,27) may be heated by continuous movement through a tunnel oven with resistance, IR radiation, gas burner or induction heating. Discontinuous lengths of tube may be heated in an oven or by introducing into the inner tube pressurised, heated fluid, e.g. steam, which also presses the inner against the bore of the outer tube.     The composite tube (24) may be connected to another tube or a fitting by expanding the tube end (25) with a mandrel, pushing it over the nipple on the fitting, which has circumferential ridges (23), and compressing the end (25) over the nipple (22) with a formtool. The tube may be secured by a tension ring (28) or a sleeve pushed back over the assembled tube end.     The fitting (21) may be of composite construction.     The outer tube (26) may be of acid-resistant steel Type 14571 (X6CrNiMo17122) or other metal or alloy pref. for stength (to resist recovery forces from inner tube) and thermal expansion.

Title: Ergometer, e.g. for training sports cyclists, - measures deformations of pedals, handlebars and seat stem independently in orthogonal directions
Inventor: WOLFRUM WERNER
IPC: A61B5/22
Filed: 1992-08-20
Abstract: The ergometer separately measures all four possible elastic deformations which can occur in a  pedal lever, i.e. bending in the rotation direction, bending perpendicular to this direction, extension  along the lever and torsion about the lever.

The force is measured at many different angular positions of the pedal.  One revolution is divided into a large number of small angle intervals, between which the force is quantised and the time recorded.  The forces acting on the steering mechanism and saddle are determined from the elastic deformations of the handlebar  and saddle stem respectively in three orthogonal directions. USE/ADVANTAGE  - For training with sports equipment, e.g. cycle. Enables optimal motions to be determined and taught to sportsman.
